mitting the application of an uninterrupted stripe to the window reveal.

The invention will be more fully understood from the followinggdescription when taken in connection with the accompanyinfi drawings and the novel features thereofwill be pointedv out and clearly defined in the claimsat the close of this specification.

Before'explaining in detailthe present invention, and the method or mode of-operationembodied therein; it is to understoodthat the invention is not limited in its application to the details ofconstruction and arrangement of parts illustrated in the ac companying drawings, since the invention is capable of other embodiments and of being practiced or. carried outin various ways. Also it is to be understood that thephrasee ology or terminology employed'herein is for the purpose of description and not of limitation, and it is not intended to limit the in.- vention beyond the terms of' the several claims hereto appended or the requirements" of the prior art.

Heretofore, it has been common practice to apply'a stripe to automobile window reveals by liandwith a pencil likebrush: The operation has been a slow-and tedious one and since the stripes have usually been' ap plied free hand, it has been impossible to apply them with any certainty of uniformity. In accordance with our invention, the stencill is clamped in place within the window reveal and an air or otherpressureoperatedi paint nozzle or brush employed to'apply the stripe, the stencil providing a continuous slot or space around the reveal where the stripe is to be applied. The operation of striping reveals thereforeis an extremely simple one when efieoted'inaccordance with our invention and'moreover, thestripes'are' uniform. Another advantage ofstriping'in accordance with this invention is that inexperienced workmen or relatively inexpensive labor can be employedto stripe the reveals.

Referring now to the drawings, A represents as a whole thestencil of our invention,

B the body panel and-C the window reveal, u

the completed stripe being shown at Sin Fig. 8.

The stencil comprises preferablya flexible portion includingtwo metal contiguous sections lOandll spaced'to provide an uninterrupted slot or opening 12 therebetween;

The'sections 10fand 11 are preferably interconnected bymeans'of a plurality of springlike members 13 which may, if desired, be

U-shaped. Theends ofthese spring mem- .1

bers may be weldedto the respective sections or connected therewith in any other suitable manner. The inner face of the section 10 is provided with a preferably.- continuous strip of fabric 14 secured thereto inany suitable manner. A plurality of preferably wooden blocks or the like 15 are securedto the outer face of the fabric strip 14 (Fig. 4), such as by glue or other adhesive material or in anyother suitable manner, these blocks extending longitudinal members or bars 16 and transverse bars 17 which are interconnected at their ends by means of strips or members 18.

. The transverse bars or end members 17 are connected to one another through the medium of additiona longitudinal members 19 which may be in the form of channel bars. The longitudinal members 16 and 19 are further interconnected by means of bars or strips 20 each of which is provided with a slot or aperture 21 (Figs. and 6).

The frame F and the section are resiliently connected together in spaced relation by means of a plurality of coil springs 22 having their opposite ends embedded in the frame and section respectively.

Each of the barsis provided with a clamping device comprising preferably a metal rod or bolt 23 carrying at its outer end a pivoted cam-like clamping member 2 1 inc uding a handle for operating it, and at its inner end with a swinging bar or member which is maintained in position upon the shaft or bolt by nuts 26.

To apply the stencil to a window reveal, the bars 25 are moved in the direction of the arrows to the position in which they are shown in Fig. 1 and the device inserted in place. As shown in Fig. 6, upon insertion of the device, the blocks or members 15 engage the inner surrounding wall of the window reveal and serve to center the stencil. Moreover, it will be seen (Fig. 6) that when the clamping members 24 are moved to the position in which they are shown in that figure, the frame F and the sections 10 and 11 of the stencil are moved toward one another against the action of the springs 22, with the bars 25 engaging the inner face of the bodypanel about the window reveal. Moreover, it will be noted that when the device is clamped in position the sections 10 and 11 are caused to flex and conform to the contour of the outer face of the body panel about the window reveal, the outer section 11 being maintained in fixed spaced relation with respect to the inner section 10 by means of the spring interconnecting members 13. hen the device is in the position of Fig. 6, it will be seen that the uninterrupted slot or opening 12 extends completely and continuously around the window reveal, this uninterrupted space being provided through the medium of the preferably U-shaped spring members 13 which maintain the sections 10 and 11 in spaced relation. WVith the stencil now clamped in position, the operator employs an air or other pressure operated paint nozzle or brush shown as a whole at D to apply the stripe to the window reveal by simply follow ing the outline of the slot 12 entirely around the stencil, thus producing a stripe such as that shown at S in Fig. 8. After the stripe has been applied the clamping members 24 are released, the bars 25 returned to the position in which they are shown in broken lines in Fig. 1 and the stencil removed from engagement with the window reveal.

Thus, it will be seen that we have provided an inexpensive stencil capable of being quickly and accurately applied to a window reveal permitting the striping operation to be effected in a minimum of time, and which may be quickly removed and applied to another window reveal to effect a similar striping operation.

We claim:

1. A stencil for use in striping automobile window reveals, comprising a frame, a flexible extension carried by said frame adapted to overlap the face of said reveal, said extension having a continuous striping space, means for centering the stencil within the window reveal, and means for clamping the stencil in position.
